Ben Lewin's moving and provocative film "The Sessions" is based on the
true story of Mark O'Brien, a paralyzed
polio victim in an iron long, played by John Hawkes, who employs a sex surrogate,
played by Helen Hunt, to lose his
virginity. As it turns out the surrogate, Cheryl Cohen Greene, still works in
that profession and has written a book about her experiences coming out in
November.
